So in my mod I made an item that when activated it will place down a tile entity block that is invisible and has the same dimensions as a lily-pad, to give the illusion that you are walking on water, in an air block on top of a water source block

 

When the item spawns the block, it sets an nbt integer of how long the block will last until it "decays." So far the blocks works great when the player is moving forward, however if the player were to stand still when the block under the player decays the held item is not fast enough to place a new one.

 

What I would like to know is how can I have it so that when the item passes onUpdate() it will "reset" the integer of the blocks instead of waiting for them to decay and place a new one

 

Test Item:

@Override
public void onUpdate(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {
if (stack.getTagCompound() == null) {
		stack.setTagCompound(new NBTTagCompound());
}

NBTTagCompound nbt = stack.getTagCompound();

if (nbt.getBoolean("active")) {
	//GET PLAYER POSITION
	int posX = (int) Math.round(entityIn.posX - 0.5f);
	int posY = (int) entityIn.posY;
	int posZ = (int) Math.round(entityIn.posZ - 0.5f);

	//PLACE BLOCKS AROUND PLAYER POSITION
	for (int x = posX - 1; x <= posX + 1; x++) {
		for (int z = posZ - 1; z <= posZ + 1; z++) {
			BlockPos posWater = new BlockPos(x, posY - 1, z);
			BlockPos posAir = new BlockPos(x, posY, z);

			//ONLY PLACE BLOCK ONTOP OF WATER/IN AIR
			if (worldIn.getBlockState(posWater).getBlock() == Blocks.water) {
				if (worldIn.isAirBlock(posAir)) {
					worldIn.setBlockState(posAir, ModBlocks.magicLilypad.getDefaultState());
				}
			}
		}
	}
}
}

 

Bridge Block (magic lilypad)

@Override
public TileEntity createNewTileEntity(World world, int meta) {
return new TEMagicLilypad(50);
}

 

Tile Entity Bridge Block

public class TEMagicLilypad extends TileEntity implements ITickable{

private int ticksRemaining;

public TEMagicLilypad(int ticksRemaining) {
	this.ticksRemaining = ticksRemaining;
}

@Override
public void readFromNBT(NBTTagCompound tagCompound){
	super.readFromNBT(tagCompound);
	this.ticksRemaining = tagCompound.getInteger("TICKS_REMAINING");
}

@Override
public void writeToNBT(NBTTagCompound tagCompound){
	super.writeToNBT(tagCompound);
	tagCompound.setInteger("TICKS_REMAINING", ticksRemaining);
}

@Override
public void update(){
	ticksRemaining--;

	if (ticksRemaining <= 0){
		worldObj.removeTileEntity(getPos());
		worldObj.setBlockToAir(getPos());
	}
}	

}

See that "//ONLY PLACE BLOCK ONTOP OF WATER/IN AIR" chunk?

 

Make it look for your own block too, and if it finds it, update the integer in the TE.

Well that was my problem, how do I update the integer?

I could make it find my block and just replace it with a new block which would set it back to the default integer but I that would probably cause problems on servers down the line

If only your te had a way for people to edit the integer... perhaps a method that when given an integer assigns it to the internal value.. setting it if you will....

but isint Public TEMagicLilypad(int ticksRemaining) { this.ticksRemaining = ticksRemaining;} a method that edits the integer when called?

 

sorry I am SUPER new to everything

https://docs.oracle.com/javaee/6/tutorial/doc/gjbbp.html

Yea was reading the link you gave me and WOOSH right over my head,

 

I probably will just have my test item replace the existing decaying blocks with new "fresh" blocks

If your item is activated against what appears to be water but really has your bridge on it, then it will probably be activating against your invisible bridge block (not the water beneath). That's possibly the case you want to detect, at which point you want to lookup the TE at that bridge's pos, validate it, and fix its ticks.

The problem is that he doesn't know how to use

world.getBlockTileEntity()

and cast it to his own object, then call a method on it.

EUREKA!!!! I believe I've done it

 

I finally got my item to update the stats of my tile entity remotely

Tile Entity

package com.armetron.crystalline_magic.tileEntity;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.ITickable;

public class TEMagicLilypad extends TileEntity implements ITickable{

private int ticksRemaining;

//Used when Tile Entity is made from Block Class
public TEMagicLilypad(int ticksRemaining){
	this.ticksRemaining = ticksRemaining;
}

//Function used to manually update the ticks remaining
public void UpdateDecay(int ticksRemaining) {
	this.ticksRemaining = ticksRemaining;
}

@Override
    public void readFromNBT(NBTTagCompound tagCompound){
        super.readFromNBT(tagCompound);
        this.ticksRemaining = tagCompound.getInteger("TICKS_REMAINING");
    }

    @Override
    public void writeToNBT(NBTTagCompound tagCompound){
        super.writeToNBT(tagCompound);
        tagCompound.setInteger("TICKS_REMAINING", ticksRemaining);
    }

    //TickRemaining is detucted every tick and block is replaced with air
    //when ticks run out
    @Override
    public void update(){
        ticksRemaining--;
        System.out.println(ticksRemaining);

        if (ticksRemaining <= 0){
            worldObj.removeTileEntity(getPos());
            worldObj.setBlockToAir(getPos());
        }
    }	

}

 

The part that was the hardest to discover is

 

TileEntity lily = worldIn.getTileEntity(posAir);

((TEMagicLilypad) lily).UpdateDecay(7);

 

I had no idea that ((class name) tileEntity) would be what edited the stored tileEntity

 

 

 

If you happen to see something that I'm overdoing, underdoing, could make more efficient then please feel free to let me know so that I may learn

woops forgot to take out the System.out.println(ticksRemaining);

 

that's what I used to see that the ticks were being updated

I had no idea that ((class name) tileEntity) would be what edited the stored tileEntity

Ha, that was the exact webpage I used

 

Thanks for the help
